Gen-2  MPX-type replacement Drop-in Barrel & Gas Block assembly:

With such a great reception to our ILWT MPX-type 9mm replacement barrels, we have decided to offer our barrel with a replacement pre-installed gas-block, for even easier end-user installation.

Our proven 4140 hard-melonite barrel, pre-installed/pinned in an Ordnance steel hardened gas-block.
All gas-block dimensions are machined within 0.0005", to correct specification, and hardened.

This option allows easy barrel-assembly swaps for end-users who choose not to remove the barrel from the gas block, during the process.

Pre-installed Barrels are available in 4.5, and 6" lengths, with 1/2-28 concentric threads for suppressor use. Thread protector is included.
You can also add a 1-peice HK-type 3-lug, machined directly onto the barrel.


Due to increase in blank prices we have to raise the prices of our assemblies as of January 2, 2018.

Please use drop-down menu for barrel length and 3-lug option, when ordering.

We use the tightest of tolerances and highest quality control.
All barrels are gas-blocks are proudly made in the USA and engraved ILWT.

Gas Port will be a matched .0625 

*As with any barrel swap, have a qualified gunsmith check head-spacing before firing.
